To all whom it may concern:

Be it known that I, Josnrn Hams, a citizen of the United States,residing at Brooklvn, in the county of New York-and State of New York,haveinvented new and useful ive feed of paper or sheets is automaticallyarrested.

Other features of the invention having been set forth in my applicationSer. No. 468,34 ofwhich the present application is. a division need notbe specifically mentioned herein.

This invention is set forth in the following specification and claim andillustrated in the annexed drawin in which Figure 1 showsa p an view of.a paper feeder embodying this invention. Fig. 2 shows'a side elevationof Fig. 1, looking from theleft. Fig. 3 shows a view of- Fig. 1 lookingfrom the left. Fig.4 is a section along line age: Fig. 1. i

In this drawing the automatic paper feeder isshown com rising aframe or.support a with a table adapted to support a pile of sheets 0. This tablecan be lifted by a screw' stem'd having miter gear connection c withratchet wheel 1. The ratchet wheel is actuated by a sawl 9 Fig. 2pivoted on'pawl arm h actuate by a link i and crank pin is on rotatingshaft m. When the pile c rises beyond a'certain level the finger. 0 onlever p swings the latter and the rock shaft 9 to which it is secured,said rock shaft carrying an intermediate lever r. A stop lever sispivoted at t and the free end of this stop 8 rests on the lever 1' or ma channeled or I sunken portion of lever 1' so as not to normallyproject above the top edge of lever r.-

A catch 2 on. arm k can then slide back and forth on-the lever r as thepawl arm h is swung back and forth by link 2'. When the lever r israised by the rising sheet ile. swinging up the lever p the stop a is tited u ward to o lever r 1g. 3. The catch'2 now swingp roject its-freeend above the face 1 ing against the stop 8 will arrest the movement ofthe pawl arm and its pawl g. The

pawl arm is loosely connected to link i so that the lmk can move whenthe pawl arm is arrested. A pin and slot connection can serve forloosely connecting the link and pawl arm. As the sheet pile diminishesthe lever p with intermediate lever r sinks to allow stop 8 to dropclear of the .catch 2 when the pawl 9 can then begin to actuate thewheel f to raise the sheet table. The arm h if leftfree will swing oroscillate by its wei ht and if in the position of'the .parts shown inFig. 2 the link 2' moves to theright it will pull arm h to the ri ht,and as the link 2' returns the arm hwifi oscillate back again unless-theswing of arm h to the left is arrested by catch 2 striking stop 8. Thesheet adhering to the rim of wheel 5 is carried forward to be taken offby roller 6 between which and roller 7 the sheet is carried off. Themouth piece {connects with a suction tube 6 but as the pneumatica'rrange- P ment is already set forth in said previous application nospecific 'mention thereof 1s necessary here. I

The mam shaft on can be actuated 1n any suitable way and can be providedwith fast and loose pulleys. The sheet table I) can be set by hand toany desired level when starting the machine. The shaft of ratchet wheelf can have a handcrank 27.

What I claim is The combination, in-a paper feeder, of a sheet support;mechanism for elevating the same including a movable member providedwith a catch; a lever; a movable stop havin an d means actuated by thesupply of sheets upon said supportfor rocking said lever, to raise saidstop end'into position to engage said catch.
